Abstract

La présente invention concerne une antenne fixe (129) et un dispositif de communication sans fil qui peuvent fonctionner sur au moins deux bandes de fréquence. Ladite antenne fixe (129) comprend un élément d'émission à deux bandes (310) qui présente une première partie d'élément d'émission (320) et une seconde partie d'élément d'émission (330) de longueur différente de la première partie d'élément d'émission (320). Elle comprend également un tronçon de ligne de syntonisation (340) qui présente une longueur axiale parallèle à un axe longitudinal central (A) de l'élément d'émission à deux bandes (310), cette longueur axiale ne dépassant pas un sixième d'une longueur totale efficace de l'élément d'émission à deux bandes (310). Un point d'alimentation (350) est électriquement couplé au tronçon de ligne de syntonisation (340) et à l'élément d'émission à deux bandes (310). En service, la première partie d'élément d'émission (320) permet de syntoniser à une première fréquence et la seconde partie d'élément d'émission (330) permet de syntoniser à une seconde fréquence.
